jackmountain;
Top of the morning to you sir, I hope that the last weekend of September was a good one for you and all in your world are well.
I was all ready to give you a glowing review of my favorite mountain rifle slings along with a link for same, whereupon I see they no longer are made....
The folks at Redi-Mag in Oregon used to make a 1" nylon "Packer Strap" which had grippy rubber bits woven right into the webbing. They came with their proprietary swivels sewn right in and and while they're not the tightest or quietest swivels in the world, they're not the worst either.
It would appear they still make a 2" version with the rubber gripper compound woven in, but no longer make the 1", which is too bad as I've tried both and believe I've given away all the 2" ones now.
I should add that about 3/4 of the time I carry my rifle on my off or left side with the muzzle down and the rest of the time it's in my hands. Since we're hunting in both rough, steep country and also very much grizzly and black bear county, I carry that way as it allows me to carry a round in the chamber but the bolt up or not closed on it. If I happen upon something up close, it allows me to swing the rifle into action with my left hand and thumb the bold closed as it's brought up to shoot.
Anyways it takes longer to type than to actually accomplish.
In the past I've tried a couple different brands of plain nylon webbing slings and all of them were much too slippery for my usual way of hunting.
If you could find an old stock 1" Packer Strap with the gripper/rubber stuff in it, they were about $16 USD usually if memory serves.
Here's a link to the new ones, but again they're plain webbing and would be light enough, but like as not too slippery for my uses.
https://www.redi-mag.com/product-category/hunting/packer-strap/The 2" one specifically mentions the gripper/rubber whatever it is.
https://www.redi-mag.com/product-category/hunting/2-2-sling-swivels/Again these aren't horrible, but I found them needlessly bulky even though they're quite lightweight still.
Hope that was useful to you or someone out there. Good luck whichever way you decide and good luck on your hunts this fall as well for sure.
